Abstract

processo e usina para produzir metanol a partir de gás de síntese rico em hidrogênio. a invenção se refere a um processo e a uma usina para produzir metanol a partir de um gás de síntese que tem um déficit de hidrogênio. uma corrente de gás de compensação de uma unidade reformadora que compreende hidrogênio e óxidos de carbono é combinada com uma corrente contendo hidrogênio de um estágio de recuperação de hidrogênio. isso produz uma corrente de gás de síntese rica em hidrogênio que tem um número estequiométrico sn, definido como sn = [n(h2) - n(co2)] / [n(co) + n(co2)], não menor que 2,0. a corrente de gás de síntese rica em hidrogênio é combinada com uma corrente de gás residual e a corrente de gás de síntese rica em hidrogênio e a corrente de gás residual são passadas por um leito de um catalisador de síntese de metanol a pressão elevada e a temperatura elevada para obter uma corrente de produto compreendendo metanol e a corrente de gás residual, e a corrente de produto é resfriada para remover metanol da corrente de gás residual. de acordo com a invenção, é fornecida uma porção da corrente de gás residual que é removida como uma corrente de gás de purga e uma porção da corrente de gás de síntese rica em hidrogênio é removida e combinada com a corrente de gás de purga para obter uma corrente de gás de síntese misturada e a corrente de gás de síntese misturada é enviada para o estágio de recuperação de hidrogênio para produzir a corrente contendo hidrogênio.
